**Measured token savings:** In a controlled 60-run study, LeanToken used 20.1% fewer model input tokens than the agent's built-in tools with limited repository exploration, and 37.6% fewer than those tools with broad exploration. See exactly how it was measured in the [measurement methodology](https://github.com/morluto/leantoken/blob/main/docs/measurement.md).

Quick start

Add LeanToken to Claude Code, Cursor, OpenCode, Codex, Gemini CLI, or Antigravity:

npx leantoken setup

Setup behavior and safety

Current releases stop setup before writing when `npx` resolves a stale project-local or ancestor install, and point to `npx leantoken@latest setup`. Older releases that predate this check can be bootstrapped directly with that versioned command.

The interactive setup wizard preselects supported clients it detects
